To ZZ whom t may concern.:

Be it known that I, EMANUEL MocrenMA, engineer, citizen of Germany, and residing at 3 Am Brgerhaus, Rheinbach, in the Province of Rhineland and State of Prussia, Germany, have invented certain new and useful Improvements in Rotating Pumps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to pumps and has particular reference to rotating pumps.

It is the main object of this invention to provide a rotating pump which is easy and inexpensive to manufacture and strong and durable in operation.

A further object of this invention is to provide a pump in which the driving means therefor is positioned eccentrically of the rotating axis of the pump piston in contradistinction to a pump in which the piston swings around a gudgeon which is mounted eccentrically to the rotating axis of the body of the pump. In this latter type of pump it is necessary that the supporting gudgeon for the pump piston be within the extension of the pump cylinder, and does not take a portion of the movement, and therefore the efciency of such pumps is greatly reduced.

Other objects and advantages of this invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which:

Figure l is a cross sectional View of the pump of the present invention.

Fig. 2 is a cross sectional view on the line A-B of Figure l.

Fig. 3 is a cross sectional view of the pump showing the piston e in a different position from that shown in Figure l.

Figure 4 is a cross sectional view of the pump showing a still further position of the piston e.

Referring now more particularly to the drawings, a represents a rotating body, preferably in the form of a disk, although it may be constructed of any suitable and desired form; the rotating body being provided with an opening b extending therethrough. The disk a is rotatably mounted within the casing CZ, which latter is provided with conducting and draining canals f and f.

Serial No. 579,598.

The opening b forms with the back of the casing Z a closed pump room in which is a reciprocating separation wheel or piston e. i

In order to effect rotating of the disk ci and the reciprocation of the piston e in the pump yroom b, a driving disk z' has been provided which is positioned exteriorly of the pump -room b, which disk is arranged eccentrically to the axis of rotation of disk a. As clearly shown in Figure 2 the piston e is supported on a bolt la which is connected to the disk z'. Also as shown in Figure 2, secured to the disk z' substantially diametrically opposite to the bolt if: is a bolt 7c which works in a groove Z. a

The disk z' is adapted to be rotated by any suitable driving means through the medium of shaft m mounted in suitable bearings, also as shown in Figure 2. It will be noted, as shown clearly in Figs. 3 and 4, that the groove Z extends substantially through the disk 0. at approximately right angles to the opening b, this groove Z providing a working surface for the bolt 7c.

From the above, it is believed that the operation of this pump will be clear and it will be seen that upon rotation of shaft m the disk t' will be rotated, shifting the piston e in the direction of the arrows shown in Figure l causing a suction at the end S and a compression at the end C. Continued rotation of the disk i will cause reciprocation of the piston e in an obvious manner.

I claim as my invention:

l. In a rotary pump, the combination with a casing, of a rotating body in said casing having a transverse groove forming part of the pump chamber, a piston movable in said casing, a disc mounted eccentrically of the axis of rotation of said body, and means carried by said disc engaging, respectively, said body and said piston for simultaneously positively rotating the body and actuating the piston.

2. In a rotary pump, the combination with an annular casing, of a. shaft entering said casing eccentrically thereto, a rotating body in and concentric with said casing, a piston reciprocable within the casing, a disc mounted on said shaft, said disc being concentric with said shaft and eccentric to said body, and means on said disc for engaging, respecdischarge passages through the pump, each of said passages tively, said body and said piston for simultaneously positlvely rotating the body and actuating said piston upon rotation of said shaft.

' 3. In Ia rotary pump, the combination with an annular Casin containing inlet and or the fluid passing with a pump easing having an extended bearing portion With a Chamber therein, of a' rotating body in said casing having a transverse groove forming part of the pump chamber, a piston 'operable in the casing, a shaft suported by the extended bearing portion of they casing, there being a duet eX tending from the chamber in said bearing portion to Within the pump casing whereby motive fluid may be returned from said chamber to the circulatory system, and means carried by said shaft for rotating said body and actuating said piston.

In testimony whereof rI have aixed my signature in presence of tWo witnesses. Y
